F 650 GS back brake sometimes does not work

[Brandt]

My 650 habe 33 000 km on the clock. My back brake sometimes does not work. I did bleed it and BMW also did bleed it last week with the service and it seems if they replaced the brake fluid. But I still have the issuue. Some one had this before?
